When I try to install it on a Nokia N8, the program compiles normally and I am getting:
the application running with pid 1897
the screen of the N8 showpreparing installation` thenfinalizing installationthenInstall`` with an ok button i press
then
a security warning that the application is untrusted
I click continue

I install the 10kb in E: Mass Memory

I am thengetting an Update error warning and a black screen
The only way to close the batteryIndicator app is to navigate among the opened app and close it from there.

I have no clue what the problem can be and «i don`t know how to investigate that issue.

Note that I have been able to install apps that I wrote with the previous SDK

yes it worked properly once I used the Nokia Smart Installer. A bit strange because I thought I had installed all the sis files from the QtSDk/Symbian/sis/Symbian^3.
Any way this installer does the job.
